Abstract: 1,203,703. Measuring fluid flow. GROVE VALVE & REGULATOR CO. Nov.19, 1968 [Nov.24, 1967], No.54898/68. Heading G1R. In a fluid flow blocking structure in which a sphere B is inserted through a passage 36, normally closed by a hinged door 38 with a pocket 34 of a rotatable ball valve 30 rotatable to the position shown in Fig.1, to release the sphere B into a prover loop 12 provided with detectors 44, 46 and then rotated through 180 degrees to receive the sphere B on travelling round the loop, the arrangement is such that a seat ring 58, surrounding each passageway 24, 26 and slidably mounted in counterbore 56 in each end plate 50, is formed by inner and outer ring members 60, 62, secured together by a snap ring 64, and which define between them a recess for a main resilient seal ring 68, also secured to the inner ring 60 is an enlarged foil portion member 70, slidable in the counterbore 56, and a sealing ring 74 is provided between the ring 60 and a member 70 and a further sealing ring between the counterbore 56 and the member 70. Coil springs 76 are disposed around the plates 50, to hold the rings 58 against the sphere 30, within an enlarged counterbore a retainer ring 78, held in place by screws 79 and provided with sealing rings 80, 82. Fluid pressure introduced from an external source through ducts 89, 90 into an annular space 88 forces the ring portions 70, 78 apart to retract the ring 58 from the valve 30 which may then be rotated and if the fluid pressure source fails springs 76 will return the ring 58 to the sealing position. The seal 68 acts on a diameter D, on the sphere 30, which is between the area formed between the diameters D 3 , of the counterbore 56, and diameter D 2 , of the scale 82.

Abstract: 1483124 Coupling torque-transmitting members BAYERISCHE MOTOREN WERKE AG 20 Dec 1974 [22 Dec 1973] ‹55132/74 Heading F2U Two components are coupled to rotate together by bodies between contacting surfaces of the components, which bodies are harder than the material of the components, formed by nitrogen diffusion into a grooved surface, and bite into this material to key them together. As shown a spacer sleeve 11 between bearing races 14 and 15 is coupled to these races by means of grooves and nitrided end faces 12, 13, axial compression of the spacer 11 by a nut 19 which biases races 14, 15, sleeve 11 and a flange 16 against a shoulder 20 of a shaft 6, on which the races 14 and 15 are mounted, causing the hardened layer to crack at the peaks between the grooves and so form the bodies which are pressed into the surfaces, as shown in Fig. 3. Instead of the ends of the sleeve 11 being grooved and hardened, grooved and hardened rings may be positioned between the ends of the sleeve 11 and the races 14, 15 (Fig. 2a, not shown). The grooves can be those created by normal machinery (of a depth of 15 to 20 Ám). The shaft 6 can be a vehicle axle shaft and the coupling prevents movement of the sleeve 11 relative to shaft 6 due to twisting of shaft 6 under torque.

Title: Defrosting Controller for Electric Refrigerator
IPC: G05D23/24
Filed: 1968-12-03
Abstract: 1,194,760. Control systems for defrosting refrigerators. MATSUSHITA ELECTRONICS CORP. 3 Dec., 1968 [14 Dec., 1967], No. 57286/68. Heading H2H. [Also in Division F4] A defrosting arrangement for an electric refrigerator comprises means for terminating the defrosting process when the frost in the freezer has been dispersed, the means for dispersing the frost being either an electric heater or a hot gas device. An electric heater 3 in a defrosting arrangement is connected to an A.C. supply by means of a thyristor 4, the thyristor being made conductive by closure of a switch 13 and non- conductive when the resistance of a thermistor 7 rises due to the absence of frost in the freezer. A transistor 5 is normally kept in conduction due to the bias voltage derived from a potential divider 9, 10 connected across the normally non-conductive thyristor 4 rectified by a diode 11 and charging a capacitor 12. To initiate a defrosting cycle the switch 13 is closed, either manually or by a timing device. Capacitor 12 then discharges through the switch 12 thereby cutting off the transistor 5. A signal thus appears at the collector of the transistor which signal is used to trigger the thyristor 4 into conduction to energize the defrosting heater 3. When the frost in the freezer is removed, the freezer temperature rises so decreasing the resistance of the thermistor 7. As the resistance of the thermistor gradually decreases the capacitor 12 begins to acquire a charge until a point is reached where the transistor 5 is once more rendered conductive whereupon the trigger signal to the thyristor 4 disappears and the heater 3 de-energized.

Title: Digital acceleration measurement device
IPC: B60T8/58
Filed: 1973-12-14
Abstract: 1396688 Analogue to digital conversion ROCKWELL INTERNATIONAL CORP 14 Dec 1973 [26 Dec 1972] 58095/73 Heading G4M [Also in Division F2] A digital signal representing the rate of change of frequency of input pulses clock 1 is derived by two accumulating registers 24, 25 connected in a negative feedback loop. For each input pulse register 24 is incremented by the digital error signal 23 and register 24 is repeatedly incremented at a fast, clock 2, rate by the contents of register 24 and cleared by the next input pulse. If the input pulses come from a magnetic toothed wheel pulse generator a bias 21 representing the distance hetween the teeth may be added at 20. Register 26 is cleared only slowly to provide an averaging effect. In a modification, Fig. 4 (not shown), a sign detector (41) detects when the error signal is negative and causes the contents of registers 24, 25 and 26 to be decreased, thus reducing the required capacity of register 25 and precluding the contents of register 24 becoming negative when the input pulse rate clock 1 goes to zero. The invention may be used in antiskid control of brakes, wherein the digital signals represent wheel speed and the output signal is used to control the brake solenoid valves.
